Is there any tool to check if a MOSFET is within its SOA or not for a given operating condition?

  • It's normally just a graph in the datasheet. – DKNguyen Feb 19 '22 at 07:19
  • The graph is only for a given temperature. Want to know if any tool is there which will convert the operational condition and calculate the point in the graph – Dibyaranjan Senapati Feb 19 '22 at 07:24

    Please numerically describe a situation where you feel that the SOA curve in the data sheet cannot yield what you want to know. – Andy aka Feb 19 '22 at 10:28
  • I'm primarily considering two test condition. First a MOSFET is used to switching (either ON/OFF) a capacitive load (100uF) from a line voltage of 100V. The second case is of a MOSFET used as a switch in a DC-DC converter (boost converter). – Dibyaranjan Senapati Feb 20 '22 at 07:32
